flfi W ATTORNEY United States Patent 2,986,961 FINGER TIP WRENCHESWilliam J. Faso, 72 E. 17th St., Huntington Station, N.Y. Filed Apr. 11,1960, Ser. No. 21,449 3 Claims. (Cl. 81-177) This invention relates tofinger tip wrenches comprising a finger embracing portion and a nutengaging portion positioned relative to each other whereby the fingertip of the user can readily position and hold a nut on a bolt in hard toreach places.

It is an object of this invention to provide such a wrench economicallymanufactured from one piece of metal.

It is another object of the invention to provide a resilient nutengaging portion.

A further object of the invention is to provide a resilient pad for thefinger tip of the user which will also aid in the resiliency of the nutengaging portion.

A still further object of the invention is to support the finger at anatural angle of inclination to engage the finger tip with the nut.

Other objects and advantages of the invention will be set forth in thedetailed description of the invention.

In the drawing accompanying and forming a part of this application;

FIGURE 1 is an elevational view showing the use of the wrench in a hardto reach place;

FIGURE 2 is a top view of the wrench;

FIGURE 3 is an end view of the wrench in elevation looking at the lefthand side of FIGURE 2;

FIGURE 4 is a sectional view of the wrench taken on the line 4-4 ofFIGURE 2 looking in the direction of the arrows;

FIGURE 5 is a sectional view of the nut engaging portion of the wrench,on an enlarged scale, taken on the line 55 of FIGURE 2 looking in thedirection of the arrows, and the resilient engagement of a nut; and

FIGURE 6 is a bottom view of the wrench.

The embodiment of the invention comprises a wrench formed from one pieceof metal, such as stainless steel, and including a finger embracingportion consisting of a split ring member 7 having wings 8 to embraceopposite portions of the finger of the user between the first and secondjoints of said finger, with an inwardly curved portion 9 below the firstjoint of the finger, as shown in FIGURE 1.

Opposite the curved portion 9 there is provided a neck portion 10connected to an annular nut engaging portion 11 of channel shape incross-section and having the inner wall provided with tapering orpointed prongs 12 inclining inwardly from the bottom wall of the channeltoward the center of the nut engaging portion whereby the prongs 12 willfrictionally engage a nut 13, as shown in FIGURE 5. The prongs 12 arespaced from each other and the outer faces of the prongs adjacent thebottom wall of the channel are flattened, as at 14 in FIGURE 6, to formcomparatively flat faces to engage the sides of the nut 13. In thepresent illustration of the invention, the nut engaging portion isadapted for a hexagon nut so that there are six prongs 12 with six flatfaces 14. The number of sides of the nut to be tightened will determinethe number of prongs and flat faces of the nut engaging portion of thewrench.

The connecting neck 10 merges with the outer side wall of the nutengaging portion 11 at an oblique angle with the nut engaging portionoffset outwardly from the finger embracing portion 7, as shown inFIGURES 3, 4 and 5.

The nut engaging portion 11 is provided with a finger gripping surfaceby inserting a ring or annular member 15 of resilient material, such asrubber, in the channel of the nut engaging portion 11. The ring 15 willalso act as a resilient butter for the prongs 12.

FIGURE 1 illustrates the use of the wrench in uniting two angle pieces16 and 17 of a frame 18 to a horizontal supporting member or brace 19 byengaging the wrench faces 14 with the sides of the nut 13 to hold saidnut against rotation while turning a screw 20 by a screwdriver 21. Theincline of the prongs 12 will prevent the nut 13 from extending entirelywithin the portion 11 while being gripped by the flat faces 14, as shownin FIGURE 5, so that the end of the screw will project from the nut asuflicient distance to tightly secure the angle pieces 16 and 17 to thesupporting member 19.

Having thus described my invention, I claim:

1. A finger tip wrench comprising a finger embracing portion and a nutengaging portion connected to the finger embracing portion, the nutengaging portion being annular and of upwardly opening channel shape incross-section and having the inner wall provided with prongs taperingfrom the bottom wall of the channel and each prong adapted to engage aside of the nut, the portions of the prongs adjacent to the bottom wallof the channel constituting the entrance to the nut engaging portion.

2. A finger tip wrench as claimed in claim 1, wherein the outer faces ofthe prongs adjacent the bottom wall of the channel are flattened tofirmly grip the sides of the nut, and the prongs incline from saidflattened faces toward the center of the nut engaging portion to limitthe movement of the nut into the nut engaging portion.

3. A finger tip wrench as claimed in claim 1, wherein the fingerembracing portion comprises a split ring member, a portion connectingthe split ring member with the outer wall of the nut engaging portionand extending in a plane parallel to the axis of the split ring memberand at an oblique angle to the outer wall of the nut engaging portionwith the open end of the channel of the nut engaging portion facing aplane in which the axis of the split ring member extends, and an annularmember of resilient material inserted in the channel of the nut engagingportion for the engagement of the finger tip of the user.
